Florida Gov. Ron DeSantis has officially entered the Twitter space ... er, presidential race. He kicked off his campaign in a conversation on a glitchy Twitter Spaces with Elon Musk and tech entrepreneur David Sacks on Wednesday. In his opening remarks, he stressed his electability and the ability to implement a policy platform that may not look all that different from that of former President Donald Trump. In this installment of the podcast, the crew discusses what DeSantis's presidential bid will look like. In FiveThirtyEight's national GOP primary polling averages, Trump currently leads at around 54 percent with DeSantis at around 20 percent, although these things can change quickly in a primary environment. In fact, they already have: Just a couple months ago, Trump’s lead over DeSantis was half of what it is today. Learn more about your ad choices. Visit megaphone.fm/adchoices

Since 1956, European countries have been gathering each year to compete in the Eurovision song contest -- a competition of largely pop and techno artists that can often feel like a parody of European tastes in music. There have long been accusations of bias in the voting process and last Saturday's competition -- which Sweden won -- was no exception. In this installment of the podcast, Galen speaks with statistics and health economics professor Gianluca Baio, who created a model to determine whether there really are biases advantaging or disadvantaging certain nations. Galen also speaks with Courtney Kennedy, vice president of methods and innovation at the Pew Research Center, who recently published a study showing that the polling industry of today bears little semblance to the polling industry at the start of the century. The days of real human beings randomly dialing landline phones are gone, but what does that mean for the accuracy of public opinion research? Learn more about your ad choices.

On Tuesday, voters are heading to the polls in at least three competitive races: the Kentucky Republican gubernatorial primary, the Philadelphia Democratic mayoral primary and the Jacksonville mayoral election. In this installment of the podcast, Galen and Nathaniel preview the state of those three races.

Title 42 is expiring on Thursday night, a pandemic-era rule allowing the U.S. government to turn away asylum seekers at the border as a public health measure. This comes at a time when apprehensions at the border are already at record highs and Americans give President Biden some of his lowest ratings on his handling of immigration. In this installment of the podcast, Galen speaks with Georgetown economics professor Anna Maria Mayda about what Americans think of immigration and why, its impacts on the U.S. and its politics, and how that compares with other countries.
